sparking plug to its junction on the distributor. Removal of thme
distributor cover should show th,e distributor arm directly beneath it.) The
dynamo coupling bolt holes should be exactly fore and aft and at right angles
to the coupling yoke on the cylinder
h,ead, and the timing marks on the
camshaft driving gears should be coinciding.
If all the foregoing are correct, replace the flexible coupling and coupling
bolts, taking care to replace the
distanc,e washers in exactly the same position
as they were originally. Tighten up the nuts firmly and rotate th'e engine
slowly by hand. If the distance washers are in th'e correct position, the
flexibl,e coupling should run absolutely true.
If
it doses not do so, note
where the error is and adjust the distance wash'ers accordingly. Th'en re-
place
th'e valve cover and attach th'e dynamo cables on to their corr~ect
terminals.
Third Brush Regulator.
'Thc output of the dynamo, that is to say, its rate
of charge, is controlled by a Third Brush which is shown quite clearly in
Illustration No.
34.
It is inadvisable for an\bodv who is not an electrician
to tamper with this, but in case th'e Amp. Meter reads more than
2
amps.
when all the head lamps are on, or in the event of its reading less than
8
amps.
when no lights are alight, the Third Rrush can be moved relative to the
armature by slackening off the nut marked
"
locking nut
"
and turning the
brush gear either towards the direction of rotation of the armature to increase
the rate of
charg'e or in the opposite direction to decrease the charge rate.
The indicated charging rate must not exoeed
8
amps. with all lights off or
severe damage will be done to the dynamo and cut-out.
The Third Brush is to he found on the n,ear side of the car- and on th'e same
side as the small ball covmered lubricator. Never omit to tighten up the lock
screw after any adjustment has
b$een efffected.
